Colgate Hum Connected Smart Battery Toothbrush Refill Head, Blue, 2 Pack

Hum toothbrushes brush so much faster and more thoroughly than I could ever do with a conventional toothbrush.

These are very soft bristles and 2 months of regular use (2x a day) wears them down. You have to replace them every 2 months

I love this toothbrush it is easy to change batteries and they last a long time. It can be attached to your iPhone to tell you if brushing properly.

Really nice to see when you miss a spot on your brushing have really enjoyed this product.

Easy travel nice compact

My HUM is green, the green heads were out of stock. These for and work fine.

Works very well and compact enough to travel with.

My kid loves using the Colgate Hum. She uses the app. She says her teeth feel cleaner than when she uses a regular brush.

This is a good toothbrush if I could change one thing, it would be to have a charging base instead of being battery operated.
